There are no known experimental data for the effects of inlet sharpness on the pipe contraction pressure loss coefficient, but there are data for intakes set flush in a plane wall which are used as approximations. Experimental data showing the variation of pressure loss coefficient with the inlet...
CC— Roughness coefficient; RR— Hydraulic radius (in meters or feet depending on the unit system) - check the hydraulic radius calculator to learn more; SS— Slope of the energy line (frictional head loss per length of pipe). It is unitless, but sometimes expressed in m/m; and kk— Co...
We can read the loss coefficent value from the literature and verify the CFD results we put to the bernoulli equation to find loss coefficient. But, my question is if we rotate the pipe system 90 degrees therefore (z1-z2)term in the bernoulli equation becomes bigger than zero. And geomet...
No exit loss if discharge is below liquid 0 0.0 Total 14.348 Kpipe=4fFLD=fDLD=0.0263(8+6+20)(1.38/12)=48.94 SumK's=14.348+48.94=63.29hF=Kv2/2g=(14.348)(4.29)2/(2)(32.174)=4.10ft of fluid Total friction loss at the discharge side of the pump (i.e. straight lengths of pipe...
We set the pipe friction number as a constant and calculate it with the input-data. The temperature, which is used in the equation, is the average of entrance and exit of pipe. Note: You can calculate gases as liquids, if the relative change of density is low (change of density/...
2 The Aramco Journal of Technology Summer 2020 Stuck Pipe Early Warning System Utilizing Moving Window Machine Learning Approach Omogbolahan S. Ahmed, Beshir M. Aman, Majed A. Zahrani, and Folorunsho I. Ajikobi Abstract / As stuck pipes continue to be a major contributor to nonproductive time...
In a simple y-junction, the head loss equation for one of the outlets would be: Total head = entry loss + tap loss + pipe loss 1 + loss in connector + pipe loss 2 + energy at exit You are correct in considering separate values of velocity (U) for before and after the junction. ...
Theoretically, the exit fluid temperature in the exothermic reactor could be as high as 473 K. Improving the performance of the exothermic reactor could lift the level of thermal energy upgrading. The thermal efficiency of the system was around 38% and the exergy efficiency was 27%. Sign in ...
The final loss function 𝐿′(𝑦𝑖,𝑦̂𝑖)L′(yi,y^i) of the training set was set to be below 5 × 10−3; the learning rate was 3 × 10−3; and the regularization coefficient λ in Equation (9) was set as 1 × 10−5. After training with 420 samples randomly ...
